The 156HC M10 NTYP SL Bifacial series is designed for investors who want to squeeze maximum energy yield out of limited roof or ground space. The module is built on N-type TOPCon technology, which, unlike older PERC cells, offers lower degradation over time and better performance at high temperatures, translating into a real gain in annual energy output. The use of half-cut cells reduces series resistance losses and improves the panel's resilience to partial shading, keeping production stable even under less favorable conditions. The bifacial design captures light reflected off the ground, making this model particularly attractive for solar farms and installations on light, reflective surfaces. Mechanical durability is supported by a reinforced frame engineered for higher snow and wind loads, while 3.2mm tempered glass adds extra resistance to mechanical damage and hail. This makes the series a solid choice for both commercial investors and developers of large ground-mount projects who prioritize low failure rates and predictable performance over the long service life of the installation.

What owners get
N-type TOPCon cell technology

N-type TOPCon cells deliver a lower degradation rate (0.4% annually after year one per the manufacturer datasheet) and better high-temperature performance than legacy PERC cells, translating into higher annual energy yield across the 25-year service life.

Bifacial design with half-cut cells

Combining bifacial construction with half-cut cells reduces series resistance losses and improves partial-shading tolerance, while also capturing albedo light reflected from the ground — a clear advantage for ground-mount installations and high-reflectivity surfaces.

High efficiency up to 23.08%

Efficiency of 22.01–23.08% places the series near the top of its segment, on par with Runergy's HY-DH156N8 (23.1%) and clearly ahead of Resun Solar's RS9K-M (22.79%) at the same 645 Wp max power.

Tier-1, North American manufacturing

Heliene is a Tier-1 bankable manufacturer with factories in Minnesota, Florida, and Ontario (Canada), and is listed on PVEL's Top Performer list. Unlike Chinese peer comparables (Runergy, Resun Solar), the module qualifies for Buy America/domestic-content programs, a meaningful factor for project financing in the US and Canada.

Reinforced mechanical build

3.2mm tempered glass and a reinforced frame engineered for higher snow and wind loads improve hail resistance and reduce failure risk in harsh climate conditions.

Trade-offs
Shorter product warranty than some N-type peers

The 15-year product warranty trails what some N-type competitors now offer (e.g., 25-year product warranties on Trina Vertex N or JinkoSolar Tiger Neo series), despite matching the industry-standard 25-year linear power warranty. This can affect bankability scoring on long-horizon financed projects.

Common questions

6 answered
What is the maximum power output of the Heliene 156HC M10 NTYP SL Bifacial panels?
Panels in this series reach a maximum power output of up to 645 Wp. This is achieved through N-type TOPCon half-cut cells combined with a bifacial design that also captures reflected light from the ground surface. As a result, this series delivers higher energy yield per unit of roof or ground area compared to comparable modules built on older PERC technology.
How does N-type TOPCon technology differ from PERC in Heliene panels?
N-type TOPCon cells, used in the 156HC M10 series, feature lower annual degradation and better performance at high temperatures compared to older P-type PERC cells. In practice, this means higher energy production during summer months and a slower decline in panel efficiency over the years, resulting in a better return on investment over the long term.
Are Heliene 156HC M10 bifacial panels worth it on a single-family home roof?
Bifacial construction performs best where the panel can capture light reflected from a bright surface, such as on solar farms, flat roofs with light-colored coverings, or ground covered with gravel or snow. On a typical sloped roof with dark tiles mounted close to the surface, the bifacial gain will be limited, though the panel still retains all the benefits of TOPCon and half-cut technology.
What warranty comes with the Heliene 156HC M10 NTYP SL Bifacial series?
The manufacturer offers a 15-year product warranty and a 25-year linear power output warranty. As a Tier 1 manufacturer headquartered in Canada, Heliene provides stable servicing conditions and predictable module performance throughout the system's lifetime, which matters both for commercial investors and homeowners planning a 20-25 year installation.
Do half-cut cells in Heliene panels improve shading tolerance?
Yes, splitting cells into halves (half-cut) reduces series resistance losses and means partial shading, from a chimney, tree, or neighboring building, has less impact on the panel's overall power output. As a result, an installation using 156HC M10 panels maintains more stable energy production compared to modules built with full, undivided cells.
How thick is the glass on Heliene 156HC M10 panels and are they hail resistant?
The panels feature 3.2 mm tempered glass, providing additional resistance to mechanical damage and hail. Combined with a reinforced frame designed for increased snow and wind loads, the module suits areas with harsher climate conditions as well as large ground-mounted installations that require low failure rates.
